JOURNAL-BOX--ALIGlNIAIiTGrl DEVICE. j

Application filed May' 21,

This invention relates to journal box aligne ing devices. i

In railway practice it has been found that the journal boxes in trucksof thepedestal type have a decided tendencyV to rotate about,

the axes of the journals, thereby gouging out the guide faces of thepedestal jaws,

eventually causing thefboxes to assume a permanently tilted conditionwhich intere 1o fcres with the proper movement thereof.

This condition is much aggravated in trucks l provided with equalizerbars which bear upon the journal boxes, for under service conditionslongitudinal movement of the equalizer bars exerts a marked tiltingaction upon the journal boxes, dition mentioned. j

An object of this invention is to provide a simple Vand efficient meansfor maintaining the journal boxes in vertical alignment in the ljaws ofthe pedestals against the tendency of vthe' same to be displaced, whilepermitting the required movement of the journal boxes, said meansincluding elements connected to each journal box which extend topointsgremote from the journal box and pedestal jaws Where they `areengaged by guide means which co-o erate therewith to permit movement ofVthe journal boxes in a vertical direction only and to prevent tilting ofthe boxes about the axes of the journal or the box under serviceconditions.

Other and further objects of theinvention will more fully and clearlyappear fromV the descri tion and claims hereinafter following. In t iedrawings forming part of this speciicatiomFigure 1 is a fragmentary sideelevational View of a truck of the pedestal type, showing the inventionin connection therewith. igure 2 is a Vhorizontal sectional view of theinvention corresponding substantially to the line 2-2 of Figure 1.Figure 3 is a vertical sectional view ofthe invention correspondingsubstantially to the line 3-3 of Figure 2. And Figure 4 is a perspectivedetailed Vview of one of the guide elements used in connection with `theinvention.

As shown in the drawings, a portion of the frame proper of a pedestaltruck is indicated at 10, said frame being provided with a plurality ofpedestal members, only one of which is shown, each pedestal membercomprising a body portion 11 and spaced jaws 12-12 providing guide faces13-13 for the journal box 14 which is slidably mounted between theaggravating the conf yoke 21.

jawslQ-lQ andvmaintained in position' by the bar 15. The jaws 12m-12 ofeach pedestal are transversely slotted as e indicated at 16l for thevreception of one end 17 of an equalizer bar 18 which bears on 'top ofthe journal box 2 in the usual manner, a spring 19 being interposedbetween the equalizer' bar 18 and the truck frame l0. 'g f Theconstruction thus far described, is of a type in common use, and no.claim. is made Y thereto except in combination with the inventionhereinafter described. In the con! struction Vjust described, thejournal box 14 moves vertically in the pedestal jaws 12-12, certainnecessary clearance being provided between the side walls "of thejournal box and the guide faces of the pedestal jaws. Under actualconditions in starting up, or stopping, the journal boxes are tiltedabout the axes of the journals because of the relative movement betweenthe` truck frame proper and the wheels and the equalizer bars, and whenruiming, the movement of each journal tends to tilt the box in `thedirection of movement thereof. The'tilting movement of the journalboxeshowever caused, gouges out the guide faces ofl thepedestals andthejournal boxes eventually assume permanently tilted positions,interfering with the proper operation of the boxes ,and necessitatingearly renewal of the pedestal members.

The present invention contemplates means for confining each journal boxVto vertical movement within the jaws of the pedestal to overcome theconditions above noted, and'said means co-operate Vwith each journal boxand the truck frame proper to hold. the box against thistiltingmovement. In carrying out the invention, the side walls of eachjournal box, at their outer ends, are provided with apertures adaptedfor the reception of trunnions 20-20, formed upon a 'detachable The yokeincludes two separate parts 22-22, each of which includes a portionfitting along the side wall `of the box, 100 upon each of which one ofthe trunnions is mounted, Each yoke member alsoincludes an angularportion indicated at 23, and the inner ends of the portions 23 areprovided with vertically projecting extensions 24e-24e. 105 The members22-22, are oppositely disposed, and are 'detachably secured together bybolts 25, which in position maintain the trunnions 20-20 in the recessesin the walls of the journal box. i

Secured in spaced relation with reference to thejournal box and the jawsof the pedestal, is a guide member in the form of a bracket 26 securedto the body portion ll ofthe pedestal by means of rivets. The outersurface of the bracket is provided with an extension providing an eye27, rectangular in cross section, in which are mounted the extensionsQe-Qfl on the yoke, said extensions being slidably disposed between thewalls forming the eye, and operatinef to prevent lateral movement oftheextensions but permitting free vertical movement thereof, therebypreventing tilting movement of the journal box.

n In this construction it should be noted that the guide member 26 islocated as 'lar from the center of thejournal box and journal,

j as practicable, and securely anrhored, thereby providing the necessaryclearance for movement of the extensions in the vguide means, while,permitting relatively small movement of the oui-nal boi; in a tiltingdi rection and hence successfully overcoming the possibility of the boxtilting in the pedestal jaws.Y i

While I have herein shown and described what I consider the preferredmanner ot carrying out the invention, the same is merely illustrative,and I contemplate allchanges and modifications which come within thescope of the claims appended hereto.

I claim:

l. In a device of the character described, the combination with a truckhaving pedestal jaws, and a journal box mounted in said jaws for slidingmovements; an equalizer bar hearing upon said "journal box; elementsrigidly connecting with said journal box and extending to a point spacedfrom said pedestal jaws and said boxgand means izo-operating with theend portions of said elements to confine the same to verticalmovcn'lent.

2. In a device of the character described, the combination with a truckframe and a pedestal member comprising a body portion and jaws, saidbody portion being secured to said truck frame; a substantiallyrectangular journal box mounted in the jaws ofsaid pedestal member forvertical movcmentf yoke means closely embracing oppositeyside edges oisaid journal box and rigidly secured thereto, said yoke means havin g'an elongated guide stem; and an elongated guidemember lined to saidtruck frame accommodating said stem, for verticalsliding movement only.,

3. In a device of the character described, the con'ibination with apedestal member and a journal box slidably mounted between the jaws ofsaid pedestal member; a two-part yoke having trunnious engageablc inrecesses in the walls of the journal bon, said yoke being;- providedwith extensions; means for detachaliily securing the parts of thev yoketo- `gether; and means co-operating with the extensions on said yokeforconfining: said extensions to movement in a. vertical direction. n j y lj Y In witness that I claim the foregoingl have hereunto subscribed myname this `17th day of May, 1927. y
